2.1 High Voltage Wire Runs
2.2 High Voltage Terminal Connections
The distance shown in the chart is measured in Feet from the operator to the power source. If power wiring is greater than the
maximum distance shown, it is recommended that a service feeder be installed. When large gauge wire is used, a separate
junction box must be installed for the operator connection. The wire table is based on stranded copper wire. The wire run
calculations are based on a power source with a 3% voltage drop on the power line, plus an additional 10% reduction in
distance to allow for other losses in the system.
“Optional” 3.3 Amp Heater Installation Note:
When installing the heater(s), refer to the
“high voltage AC power wire size and
distance requirements”
table on the instruction sheet with the heater kit (P/N 6550-480) for AC power wire run requirements.
This table illustrates the high voltage wire size and distance requirements for a single operator.
Reduce the wire distance in half for a primary/secondary dual gate operator application

•
Route incoming high voltage power through conduit and
into the operator as shown.
•
Be sure wiring is installed in accordance with local codes.
Be sure to color code all wiring.
•
It is recommended that a surge suppressor be installed on
the high voltage power lines to help protect the operator
and circuit board from surges and power fluctuations.
•
Secondary operator in a dual operator application gets AC
power through the 8-wire interconnection cable that
connects the 2 operators together. See next page.

DANGER
HIGH VOLTAGE!
DO NOT
cycle the operator without the OPEN and CLOSE limit sensors in their specific open
and close positions.
The limit sensors or the AC power switch are the ONLY ways to stop the operator once
an open cycle has started. This could cause damage to the gate and/or operator if the gate opens too far!
